PRODUCT DESCRIPTION
The alloy is usually produced by VM / CVM followed by electroslag refining (ESR), Vacuum Arc Melting (VAR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' specific requirements.
Round bar / Disc (diameter): 5.5mm to 800mm
Square bar / Flat bar: 10mm to 400mm
Length: Fixed length or random length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T60 - 400mm X W100 - 1000mm X L1000 - 6000mm
Forging piece: stepped shafts, other different shapes based on OEM.
